24 Workers' Compensation Statistics Every Employer Should Know
How many workers get hurt on the job, what claims cost by cause of injury, what insurers pay in benefits, and why coverage is required, in 24 cited statistics for U.S. employers.
Workers’ compensation is the oldest social insurance program in the United States, and for most employers it is not optional. It pays the medical bills and a share of lost wages when an employee is hurt on the job, and in exchange it shields the business from being sued over that injury. This report pulls together 24 cited statistics on how often workers get hurt, what workers’ compensation insurance claims cost by cause of injury, what insurers pay out in benefits, and how the market prices the coverage. Every figure comes from a federal agency, a regulator, or an insurance research body, never a sales page.

How often workers get hurt
1. Private employers reported 2.6 million injuries and illnesses in 2023
Private-industry employers logged 2.6 million nonfatal workplace injuries and illnesses in 2023, down 8.4% from 2022. That total is the running tally of recordable cases that drive most workers’ compensation claims. While the number is large, the trend is encouraging, because both the count and the rate have been falling for years as workplaces get safer. Each recorded case still represents a worker who needed medical care, time off, or both.
2. The injury rate is the lowest in 20 years
Beyond the raw count, the rate tells the real story. The total recordable case rate fell to 2.4 cases per 100 full-time-equivalent workers in 2023, down from 2.7 in 2022 and the lowest in the data series going back to 2003. A declining rate means the drop is not just an artifact of a smaller workforce. Better training, automation, and ergonomics have steadily pushed injury frequency down across most industries.
3. Nearly a million cases required days away from work
Not every injury keeps a worker home, but a large share do. About 946,500 private-industry cases in 2023 involved days away from work, the more serious injuries that typically generate indemnity claims for lost wages. These are the cases that cost insurers the most, because they combine medical treatment with wage-replacement payments. The remainder are medical-only or restricted-duty cases that resolve more cheaply.
4. Falls, slips, and trips drive 479,480 cases
Among specific events, falls, slips, and trips are one of the largest single causes. They accounted for 479,480 cases involving days away from work in 2023, with a median of 13 days away. These injuries hit nearly every industry, from construction to retail to offices, which is why they are a perennial target for safety programs. The long median absence shows why fall claims are both common and costly.
- Days away from work 36%
- Other recordable cases 64%
Fatal work injuries
5. There were 5,283 fatal work injuries in 2023
The most serious outcomes are tracked separately. There were 5,283 fatal work injuries in the United States in 2023, a 3.7% decrease from 5,486 in 2022. Workers’ compensation pays death benefits to the dependents of these workers, covering lost income and funeral costs. The decline is welcome, but the figure still averages more than 100 worker deaths every week.
6. The fatal injury rate was 3.5 per 100,000 workers
Adjusted for the size of the workforce, the fatal work injury rate was 3.5 fatalities per 100,000 full-time-equivalent workers in 2023, down from 3.7 in 2022. The rate matters because it lets safety officials compare risk across years and industries regardless of employment swings. A falling rate confirms that the long-term improvement in workplace safety is real and not just a function of headcount.
7. Transportation incidents are the leading cause of death
The single deadliest category at work involves vehicles. Transportation incidents caused 1,942 fatalities in 2023, or 36.8% of all work-related deaths, making it the most frequent fatal event. This is why driving exposure weighs so heavily in workers’ compensation pricing. The next largest causes were falls, slips, and trips at 885 deaths and workplace homicides at 458.
8. Transportation and construction occupations see the most deaths
Risk is not spread evenly across jobs. Transportation and material-moving occupations had the most deaths in 2023 with 1,495 fatalities, 28.3% of the total, followed by construction and extraction occupations with 1,055 deaths, or 20.0%. These two groups alone accounted for nearly half of all work-related fatalities. That concentration is exactly why workers’ compensation rates for trucking and construction sit far above those for office work.
What claims cost by cause of injury
9. Motor vehicle accidents are the most expensive claims
Cause of injury is the biggest single driver of claim cost. Motor vehicle accidents produce the most expensive lost-time workers’ compensation claims, costing about 70% more than the average lost-time claim. They tend to involve multiple body parts and longer recoveries, which inflates both medical and wage-replacement costs. A single severe crash can cost more than dozens of routine claims combined.
10. Motor vehicle accidents are only 5% of claims
The cost story is striking precisely because volume is low. Motor vehicle accidents make up just 5% of all lost-time workers’ compensation claims, yet they carry the highest average severity of any cause. That mismatch between frequency and cost is common in insurance, where a small slice of severe events drives a disproportionate share of losses. It also explains why insurers scrutinize a business’s driving exposure so closely.
11. Severity ranks motor vehicle, then falls, then burns
NCCI ranks average lost-time claim severity by cause, and the order is consistent. Sorted from most to least costly, the leading causes are motor vehicle accidents, then slips and falls, then burns, then strains, then contact injuries. The ranking reflects how serious each injury tends to be rather than how often it happens. Strains are far more frequent than burns, for instance, but cost less per claim on average.
12. Medical and indemnity severity each rose 6% in 2024
Even as fewer claims are filed, the ones that occur are getting pricier. In 2024, medical claim severity rose 6% and indemnity claim severity rose 6% as well, according to NCCI. Medical inflation, longer treatment, and rising wages all push severity higher. This is the core tension in the line: frequency keeps falling while the cost of each remaining claim keeps climbing.
13. Claim frequency has fallen about 5% a year for a decade
The long decline in injuries shows up directly in claim counts. Lost-time claim frequency has dropped at a compound annual rate of about 5.1% from 2014 through 2023, and fell another 5% in 2024. Fewer claims is the main reason the line has stayed profitable despite rising severity. Safety technology, automation, and an aging-out of the most hazardous manual jobs have all contributed.
14. Severity has risen about 4% a year over the same period
The other half of the equation is cost per claim. Over the same 2014 to 2023 window, severity climbed at a compound annual rate of about 4.4%. When you combine a roughly 5% annual drop in frequency with a roughly 4% annual rise in severity, total losses stay relatively flat. That balance is why workers’ comp pricing has been comparatively stable while other insurance lines have spiked.
What the system pays out
15. Benefits paid reached $61.7 billion in 2022
The payout side of the system is large. Workers’ compensation paid $61.7 billion in benefits in 2022, split between medical care for injured workers and cash benefits that replace lost wages. That figure represents real money flowing to people who were hurt on the job and the providers who treated them. It is the entire reason the coverage exists.
16. Medical and cash benefits are split about evenly
The mix of what gets paid is roughly balanced. Of the 2022 total, $29.0 billion went to medical benefits and $32.7 billion went to cash benefits that replace lost income. The near-even split shows that workers’ compensation is as much a wage-replacement program as a health-coverage one. Both halves matter to an injured worker trying to recover without losing their household income.
- Cash (wage replacement) 53%
- Medical care 47%
17. Benefits equal about $0.60 per $100 of covered wages
Measured against payroll, the cost of benefits is modest and shrinking. Benefits paid came to about $0.60 per $100 of covered wages in 2022, down over the prior five years. This ratio is the standard way researchers track the system’s generosity over time. The long decline reflects falling injury rates more than any cut to individual benefits.
18. Employer costs hit $103 billion in 2022
Employers pay considerably more than workers receive in benefits, because their cost also covers insurer expenses, claims handling, and profit. Total employer costs for workers’ compensation were $103.0 billion in 2022, up 1.4% from the prior year. That works out to about $1.00 per $100 of covered wages. The gap between $103 billion in cost and $61.7 billion in benefits is the friction of running the system.
19. The program covered 146.3 million jobs
The reach of workers’ compensation is nearly universal among employees. The system covered about 146.3 million jobs in 2022, spanning private employers and most state and local government workers. That broad coverage is the point of a mandatory social-insurance program: almost anyone hurt at work has a benefit path. The few gaps tend to involve very small employers, certain agricultural work, and independent contractors.
Why coverage is required and how it is priced
20. Workers’ compensation is administered by the states
The legal backbone of the coverage sits at the state level. Workers’ compensation for employees of private companies and state and local governments is administered by individual states, each with its own rules on benefits, eligibility, and which injuries are compensable. Separate federal programs cover federal employees, longshore workers, and energy and coal-mine workers. This is why requirements, rates, and benefits vary so much from one state to the next.
21. It replaces wages and pays for medical care
The benefit structure is what employers are buying. Workers’ compensation provides medical care for work-related injuries and illnesses, wage-replacement benefits while a worker recovers, and death benefits for the dependents of those killed on the job. In return, the system is generally the exclusive remedy, meaning an employee accepts these set benefits instead of suing the employer. That trade-off protects both sides and is the reason the coverage is mandated.
22. The 2024 combined ratio was 86%
The line is one of the healthiest in property and casualty insurance. Workers’ compensation posted a calendar-year combined ratio of 86% in 2024, meaning insurers paid out 86 cents in claims and expenses for every premium dollar. A ratio under 100 signals an underwriting profit, and workers’ comp has now run profitably for more than a decade. That stability is good news for employers, because it tends to keep rates from spiking.
23. Net written premium fell 3% in 2024
Strong profitability has fed back into lower prices. Workers’ compensation net written premium decreased 3% in 2024, as competitive pressure and falling claim frequency pushed rates down. Premium had grown in prior years on the back of rising payrolls, so the 2024 dip reflects rate cuts more than a shrinking economy. For employers, soft pricing means now is a favorable time to shop the coverage.
24. The line has been profitable for over a decade
The 2024 result was not a one-off. Workers’ compensation recorded its ninth consecutive year of underwriting profit in 2023 with a combined ratio of 87, its second-best result in 20 years, and the streak continued in 2024. A run of profitability this long is rare in insurance and reflects the steady decline in claim frequency. It also gives insurers room to compete on price, which benefits employers buying coverage.
How to get workers’ compensation coverage for less
The data points to a clear playbook. Workers’ comp is required almost everywhere, but the price you pay still depends on your industry, your claims history, and how hard you shop:
- Know your class code. Rates hinge on the cause-of-injury risk in your trade, so a misclassified payroll can cost you. Confirm your classification before you renew.
- Cut driving and fall exposure. Motor vehicle accidents and falls are the costliest causes of claims, so safety programs that target them lower your experience rating fastest.
- Compare insurers before you renew. With the line running at a combined ratio of 86%, carriers are competing on price. Start with our carrier comparison and then compare quotes.
- Check your state’s rules. Requirements and rates are set state by state, so review the workers’ compensation directory for your location.

Frequently Asked Questions
Is workers’ compensation insurance required?
In almost every state, yes. Workers’ compensation is administered by the states, and the large majority require employers to carry it for their employees, with separate federal programs covering federal and certain maritime and energy workers. The coverage is mandated because it provides medical care and wage replacement to injured workers while shielding employers from lawsuits over those injuries.
How much does the workers’ compensation system pay out?
A great deal. Workers’ compensation paid $61.7 billion in benefits in 2022, split roughly evenly between $29.0 billion in medical care and $32.7 billion in cash wage replacement. Employers paid even more to fund it, with total employer costs reaching $103.0 billion that year.
What kind of injury costs the most?
Motor vehicle accidents. They produce the most expensive lost-time claims, costing about 70% more than the average claim, even though they are only about 5% of claims. Slips and falls rank next for severity and are far more common, which is why both are top priorities for any workplace safety program.
How often do workers get hurt on the job?
Less often than they used to. Private employers reported 2.6 million nonfatal injuries and illnesses in 2023, with an injury rate of 2.4 cases per 100 workers, the lowest in two decades. Separately, there were 5,283 fatal work injuries that year, most of them caused by transportation incidents.
Why are workers’ compensation rates falling?
Because the line is very profitable and claims keep dropping. Workers’ comp ran at a combined ratio of 86% in 2024, and net written premium fell 3% as insurers competed on price. Lost-time claim frequency has declined about 5% a year for a decade, giving carriers room to cut rates even as the cost of each claim rises.
